点击gridView 底部出现的默认效果去掉

方法一：初始化的时候在代码里面设置
gridView.setSelector(new ColorDrawable(Color.TRANSPARENT));

方法二：

<GridView android:id="@+id/all_apps"
        android:background="@drawable/application_background"
        android:persistentDrawingCache="animation|scrolling"
        android:alwaysDrawnWithCache="true"
        android:scrollbars="none"
        android:drawSelectorOnTop="false"
        android:listSelector="@drawable/grid_selector"
        android:numColumns="auto_fit"
        android:columnwidth="78dp"
        android:stretchMode="spacingWidth"
        android:layout_weight="1.0"
        android:layout_height="0dip"
        android:layout_width="match_parent"
        android:stackFromBottom="true"
        android:visibility="invisible" 
    />
    在GridView属性中注意上面绿色的那一行.它指定了元素的背景布局文件为dwawable目录下面的grid_selector.xml文件.打开grid_selector.xml文件,有下面的描述:

    <selector xmlns:android="

gridview android
